USB sticks

below you will find a list of "good" & "bad" USB-sticks - please fill in your experiments

There is a lot different USB-devices on the market, which difference both in what they identify as (USBClass), how they communicate with the desk (USB Subclass), and the filesystem format of the diskspace to write your data to.

The grandMA OS (VxWorks) is not a plug-n-play OS, so if stick needs special installer etc it may be unsupported.

If you are having issues with USB-sticks, please take the following precuations before dedicating a specific stick to use for the grandMA


"USB stick must be formatted as FAT32. There are various formatted sticks out there, and a suspicion that other FATs can course trouble or will not work at all."

"Not supported Subclass 2(SFF8020I), which is normally used for CD/DVD devices.

Unfortunately there are such sticks at market.

Partly supported Subclass 5 (SFF8070I), not tested yet.

Full supported Subclass 6 (SCSI), which are most sticks and drives."
